Cladding Flanges,Cladding pipes,Cladding fittings, A694 F42, F52, F60, F65, F70, Inconel® 600/625 & Incoloy® 800/825.

CLAD is a composite technology of metallurgy for two kinds of different metals. We can make overlay welding on most carbon, low alloy, chrome moly, stainless steel and other steels with variety of corrosion resistant alloy including Inconel®, Incoloy®, Monel®, Hastelloy®, stainless steel and hard facing steels. Benefit from our advanced computer controlled welding stations, we offer very low dilution of alloy deposite. Real time video monitoring and recording system ensure perfect tie in and weld path.Why CLAD

Zhongzhou Special Steel  Quality Assurance
Our experienced and qualified technicians utilize NDT techniques to ensure high quality and reliability of our products during the weld overlay process. Final documents for clients will be issued, including all inspection process recordings and procedures.

  • Radiographic inspection - RT

RT test is carried out by 3rd party professional RT testing company at the cost of Zhongzhou Special Steel  .

  • Dye penetration test- DPI

All components are subjected to penetrate testing prior to overlay deposition and on completed items. Remote video-probe inspection technology is utilized on inspecting internal bore diameters of pipe. We are able to examine inside length of the pipes up to 6.5 Mtr.

  • Positive Material Identification – PMI

We utilize the world's best 26-channel portable online PMI device to recheck chemical composition of the base material and cladding layer. The test reports will be completely saved in the computer on PMI device and can be traced. Shanghai Research Institute of Materials and the imported specimen ensure the PMI accuracy.

  • Ultrasonic Testing – UT

We utilize the world`s advanced wave and standing wave detector to do the ultrasonic testing on the integrity of the weld overlay layer and the base material to guarantee the cladding quality. Zhongzhou Special Steel  strictly comply to the customer`s measuring standards of cladding thickness.

  • Magnetic Particle Testing- MT

We utilize fluorescence or visual techniques to test the surface defect on ferromagnetism components after all production phases are completed.

  • Visual Test-VT

Using remote video camera techniques and through the outlay screen, we can examine the cladding appearance and record the VT process media. VT process media will be submitted to the customer as part of the quality assurance documentations.

  • Clad Layer Thickness Checking

Innovative equipment will be used for the CRA clad layer thickness checking, such as the Inconel 625 layer welded on the carbon steel and low alloy steel. The clad layer of the pipes or  bends will be checked continuously to meet customers` requirements.
Nowadays, our own Butt Weld WPS/PQR already covered C.S, Low Alloy High Strength Steel, Austenitic Stainless Steel, Super Austenitic Stainless Steel, Duplex Stainless Steel and Cladding Steels, so we can also provide shop pre-fabrication; Shop hydrostatic testing pressure up to 10,000 PSI;

Persisting in "High high quality, Prompt Delivery, Aggressive Price", we've established long-term cooperation with clients from the two overseas and domestically and get new and old clients' superior comments for Cladding Flanges A694 F42 Inconel 625. The product will supply to all over the world, such as: Fiji,Benin,Brazil. Besides there are also skilled production and management advanced production equipment to assure our quality and delivery time our company pursues the principle of good faith high-quality and high-efficiency.
